Ubuntu Security Notice USN-681-1
1st December, 2008
imagemagick vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 7.10
- Ubuntu 6.06 LTS
Software description
- imagemagick
Details
It was discovered that ImageMagick did not correctly handle certain
malformed XCF images. If a user were tricked into opening a specially
crafted image with an application that uses ImageMagick, an attacker
could cause a denial of service and possibly execute arbitrary code with
the user's privileges.
Update instructions
The problem can be corrected by updating your system to the following package version:
- Ubuntu 7.10:
- imagemagick 7:6.2.4.5.dfsg1-2ubuntu1.1
- Ubuntu 6.06 LTS:
- imagemagick 6:6.2.4.5-0.6ubuntu0.8
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system upgrade you need to restart any applications that
use ImageMagick, such as OpenOffice.org and Inkscape, to effect the
necessary changes.
